C#中pictureBox上如何设置label透明

在pictureBox的Paint事件中写下如下代码

private void pictureBox1_Paint(object sender, PaintEventArgs e)

{

foreach (Control C in this.Controls)

{

if (C is Label)

{

Label L = (Label)C;

L.Visible = false;

e.Graphics.DrawString(L.Text, L.Font, new

SolidBrush(L.ForeColor), L.Left - pictureBox1.Left, L.Top - pictureBox1.Top);

}

}

}

或者在载入页面的时候在LOAD中写入下面代码：

pictureBox1.SendToBack();

label1.BackColor = Color.Transparent;

label1.Parent = pictureBox1;

label1.BringToFront();
